Patented Aug. 20, 1907.

Application filed December 4,1905. Serial No. 290,066.

To all whom'it may comcrn:

Be it known that I, FRANK M. Terms, a citizen of the United States,residing at Chicago, (oolc count y, in the'State of Illinois,havoinvented certain new and useful Improvements in Sugar-WaferMachines. of which the following is a full, clear, and exactspecification.

My invention relates to improvements in machines for producing sugarwafers and analogous products. and the same has forits object moreparticularly to provide a. simple, eflicient and reliable apparatus forapplying the lilling material or paste to the water shoots. and thenduly spreading the same thereon.

These objects above set forth I am enabled to at lain by means or myinvention which consists in the novel details of construction and in thocomhination. on nection and arrangement of parts hereinafter morc fullydescribed and then pointedont in the claims.

In theorccompanying drawings forming part of this specification, whereinlike numerals oi rcierence indi cate like parts, Figure 1 is a side\'ic\\'. partly broken out, showing a sugar wafer machine provided witha coating and spreading apparatus constructed according to and embodyingmy invention, Fig. l i.

an enlarged 2 of Fig. 3. illustrating the paste hopper and relatedparts: Fig. ll is a similar view tak n on the line 3-3 ul Fig. 2,showing said hopper and parts in end view; Fig. l is an enlarged partialend view of the paste receptacle partly lu-olccn l away to show theplate lor controlling the How of paste. and the securing and indicatingmeans thcrcl'or; Fig 5 is a. section of the same taken on the line F .i.said Fig. 4; Fig. 6 is an enlarged detail side view oi portion of themachine showing the gear and sprocket mechanism foroperating the samc,and Fig. 7 is a section oi the same taken on the line 7--7 oi said Fig.(i.

In said drawings 10 designates a frame having a top plate 11 arrangedthereon above which and between the longitudinal guides '12 is arrangedan endless hand 01 conveyor lii working upon transverse rollers l4, i larranged at opposite ends of the inacl inc, the rollers l4 beingadjustahly mounted so as to permitof the adjust ment of said band orconveyor l3.

Below the top plate l l and near one end of the frarn 10 is supported amain driving shalt l5 having a pnllc y 16 fixed thereon over whichpasses a driving belt 17. 18 denotes a gear wheel fixed on said maindriving shaft 15 which meshes with a large gear wheel '19 on a shaft 20supported above and to the left of the main driving shaft 15, and 21, 22denote sprocket wheels fixed upon said shaft 20 near its forward end.

23 denotes a sprocket chain extending from the sprocket wheel 22 to thesprocket 'WhOGl 24' of the roller 14, and 25 a sprocket chain extendingfrom the sprocket wheel 23 to a sprocket wheel 26 fixed on a shaft 27.

At the npperleit hand end oi the heme 10 are secured vertical ln'ackcts28, 28, in which are -.rdiuslably mounted the ends of shafts 29, 29carrying rollers 30', 30 over which passes an endless band 3].

S2 donotcs a gear wheel lined at one end of the shaft 29 which gearwhccl is actuated by the gear wheel 33 on the shalt 27 throughtheintermediate gears 34, 35, 36.

Adjacent; to thc roller 30 is arranged the mechanism for depositing andspreading the paste upon the wafer shcct. and the same consists of airamc comprising two side members 37 each having upwardly and outwardlyextending arms 3b. 3b connected by transverse rods :45 34).

4t) denotes a paste hopper which is pivotally supportcd at one of itsides upon one of the ransverse rods 39 and its opposite side adapted torest upon the other of said rods and he securcd thereto by a lockingdevice -l l. The hoppcr it) is (o-extensive in Width with the endlessbelt or convcycr l? and is entirely open at its bolt-mu so that thepaste or lilling material therein may he dcpositcd directly upon thewafer sheets as the same are carried under said hopper upon the bclt orcon- Yeycr lil. Within said hopper near ils bottom is arranged a tlatgate or valve 42 which is pivotally sccured atits upper edge to'sa idhopper and itslowcrcdge tree and extending to the lower edge of saidhopper, and -13 denot( an arm lixed to one end oi a shaitor trunnion towhich said gate or valve 42 is secured whereby the lower edge thereofmay bc adjusted or set to control the amount of paste discharged fromthe hopper.

it denotes a scgnu-nt-.tl gage plate provided with'a rack H which thedetent 45 is adapted to engage to hold the gate or valve 12 to itsadjusted position, and

indicate the extent. of its opening. and 45 a linger portion of saiddetour t by mcans of which said dctent; 45 may be rcle 'cd of itscngagcmcnt with the rack 44 Within the hopper l0 and at one side thereofnear its top is arranged a shalt in having one end extending through theside of said hoppcr and provided with a crank 47 to the outer end olwhich is pivotally secured the upper end ol a rod in whose lower end ispivotally secured to the gear whet-l 2H. Upon the portion of the shaft4t) within the hopper are tixcd the upper ends of arms 49 which areunited at their lower ends by a blade 50.

Along the lower edge of the hopper opposite to the side to which thegate or valve 12 is secured is arranged a plate M which is pivotallysecured along its upper edge to said hopper and at the middle of itsouter edge is pivots-lily secured one end of a screw 52 Whose upper endextends through an aperture in a transverse bar 53 which is pivotallysupported at; its ends in the projecting side portions of the hopper 40.

5-1 denotes an adjusting nut secured upon the screw 52 above the bar 53,and 55 a spring disposed upon said screw intermediate the adjustingplate 51 and the bar 53.

the amount or thickness of thl: paste discharged l'rom the hopper.

At the right hand end of the machine is shown the mechanism for unitingthe sugar-wafer sect ions into one structural mass, and the sameconsists of two transverse rollers 56 56 mounted in bearings 57, 57secured upon the frame 10, and 58 denotes an endless belt or bandpassing over said rollers 56, 56. Upon the frame 10 intermediate therollers 56, 56 are secured bracluel's 59 59 within which are arranged afixed pressure plate 60, and an adjustable plate 61 bet ween which thelower pertioncf the belt 58 is adapted to pass. At one end of the shaltof the roller 56 is mounted a gcarn'lmel (l2 meshing with a similar gearwheel (33 on the shah. oi the roller 14 arranged within the framedirectly below the roller 56. I

The operation of the machine is as follows: Assumingthe machine to be inopt-ration, and the endless bolts 13, 30, and 58 to be moving in thedirccl ion of the arrows (Fig. 1), it simply becomes necessary to openthe gate or valve 42 within the hopper .0 to the required extent whichwill be indicated by the gage 15 thereon; adjust the spreading blade 54by means of the adjusting screw 52 and nut 51 and then .t'eed the wafersheets into the machin upon the conveyor 13. The paste will thereupon becaused to issu from the li0} )l')ll through the transversely opt-nbottom of the hopper, and be depositedupon the wafer sheets as the samepass under said hopper, and spread under pressure upon said wafer sheetsin the .iorm oi an even, uniform layer by the sprin pressed lower end ofthe blade 54 Ilereupon the upper wafer sheet is disposed upon saidcoated layer, and the whole united by pressure of the platcs (it), til,as the same is caused to pass between said plates, and iulcrmodiatttheendless band 58 and conveyer iii. In the operation of the machine thepaste in the hopper 40 is constantly agitated by the action of the armsl) and blade Fit), which agitator also serves to cause the paste toissue uniformly iron) the open lower portion of the hopper.

'lheamount oi paste deposited and spread upon the wafer sheet may beregulated or controlled by means of the gate or valve 42 and thepivoted. blade 54, the adjustment of which is to a certain cxtc-ntdependent upon the speed with which the wafer-sheets to be coated arecaused to travel below the hopper upon the conveyor 13.
